On September 14, 2007, about 1500 Pacific daylight time, a Cessna U206G, N5344U, overran the runway and came to rest in a ditch at the Fort Bragg Airport, Fort Bragg, California. The pilot was operating the airplane under the provisions of 14 CFR Part 91. The commercial pilot sustained minor injuries. The airplane sustained substantial damage. The personal flight departed a private airstrip in Laytonville, California, about 1445, with a planned destination of Fort Bragg. Visual meteorological conditions prevailed, and no flight plan had been filed. In a written report to the National Transportation Safety Board, the pilot stated he landed, overran the 1,850-foot runway, and came to rest in a ditch on the departure end of the runway. Review of the airplane's landing performance chart revealed that if the pilot landed the airplane at maximum gross weight with full flaps extended, a ground roll of about 740 feet would have been required to stop. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine. The aircraft sustained substantial damage, including structural damage to the firewall and right wing.
